WINDOW SHADE.

vApplication led November 26, 1926. Serial No. 150,914.

This invention relates to certain novel imhousing 18 Within which is arranged a filler provements in window shades and more parcore 19 car ing a trunnion 20 which is ticularly to a window shade utilized for peradapted to e positioned in an openin mitting ventilation within a room while formed in the plate 16. Secured to the fillobstructing view therewithin and has for er core 19 is oneV end portion of a spring 60 its 'principal object the provision of an im- 22 arranged about a rod 21. The opposite ,proved construction of this character which end portion of this spring is secured to the will be highly eficient in use and economirod 21 in a well known manner. This rod cal in manufacture. 21| has a trunnion 23 which is adapted to l Other objects will appear hereinafter. engage in an opening formed in the adjacent 65 The invention consists in the combination plate of the plates 16. This trunnion 23 and arrangement of parts to be hereinafter 1s substantially rectangular in cross section described and claimed. and projects through an opening23 formed The invention will be best understood by in a core 24. This core 24 removably supreference to the accompanying drawings ports a pin 25. This pin 25 is utilized for 70 illustrating the preferred form of my inretaining the spring under tension when the vention, and in which: roller is not disposed in an operative posi- Fig. 1 is an inside elevational view of a tion with its trunnions engaged in the holes window construction showing the invention of the plates 16.

Each of the shades 24 has a plurality of Fig 8 is a part sectional detail view of a openings 31 formed therein for. reason here# f guiding arrangement embodied in the in inaft-er set forth; thus making each of the vention,.and shades a reticulated member. D .Fig 9 is a fragmentary end elevational As shown in Fig. 2the shades are arranged 95` View of the guiding arrangement illustrated in parallel relation with respect to each in Fig, 8. other and the outer shades indicated at 24 l In the drawing, 10 indicates a window have their lower end portions' 25 secured construction with which my invention is asto sleeves 32 in substantially the same mansociated. This window construction includes nerl as securing each -of the shades to their 100 side jambs 11 havinglongitudinal grooves respective rollers. These sleeves are formed 12 formed therein. Arranged in each of as an integral part of a sleeve 33 which these grooves 12 is a guiding structure 13.` sleeve embraces a stifening sleeve 34. The This guiding structure 13 includes a back inner shadel indicated at 25b has its lower plate 14 having' secured thereto guide chanend portion 37, F 1g. 2, connected t0 the 105 nels 15 for reasons hereinafter set forth. sleeve 34 in the same manner'as its upper Secured to the side jambsare roller supend portion is secured to the housing 18. porting plates 16 which support the rollers Slidably arranged wvitliin the stiening 17 in offset position with respect to each sleeve 34 are aligned operating rods 38 carother. Each of these rollers 17 includes a rying at their outer end portions guiding 110 arms 39. Embracing theoperating rods 38 are spring members 40 which have their outer end portions 41 abutting projections 42 which afford connection between the arms 39 and the operating rods 38. The inner end portions 43 of the springs bear against an annular flange 44. Thus it will be seen that the springs 40 function to retain the guide arms 39 in their outer positions. The guide arms 39 carry rollers 44 which work within the intermediate guide channels and sel-adjustably connected to the guide arms are retaining plates 45 dwhich engage the bight portions of the intermediate channel tion the rollers 17 have -their trunnions ar. ranged in their respectlve openings formed in the plates 16. When the shades are guides 15. These retaining plates 45 havel formed therein diagonal slots 46 and passing through these slots 46 are pins 47 which provide slidable connection between the guide arms 39 and the retaining plates 45.

Means i's provided for moving the guide arms 39 toward each other and in the present instance this means includes fingers 52" which project through a slot 53 formed in the sleeve 34 and have their inner end porlowering the shades tions connected in a Vsuitable manner to the blocks 38 which are secured to the operating rods 38. Thus it will be seen that by disposing the fingers 52 between the thum and index finger of the hand in one instance, the lingers. 52 will be moved toward each other whereby to move the operating rods 38*y against the action of the spring 40 to disengage the guide arms 39 from holding position within the channels within which they engage.

Means is also provided for raising and and 'for moving the arms from their operating position within the guide channels when the shades are disposed in such'positionthat the fingers 52 cannot be reached and lin the present in stance this means includes depending armsl 47 which are secured to the operating rods 38 through the medium of the blocks 38. These arms 47 extend downwardly through slots 48 formed in the sleeves 33 and 34 and connected to the outer end portions of the arms 47 is a lazy tong 50b By operating the lazy tong in a well known manner the operating rods will be moved toward each other and during this movement move the guide arms from bearing relation with respectto the intermediate lingers 15 while at the same time permitting convenient raising and low'er'ing of the shades.

As shown in -F ig. 2 the outer shades 24 have connected thereto guide strips 51 which lnip'ositioning the shades in proper posi- -atmospheric air enters through the opening ot' the window construction it will'v take a zig-zag course and be somewhat retarded as it emerges through the openings of the inner of the window shades. Thus it will be seen that when the window sash of the win-A doT construction is open and the shades are arrangedv over the opening the draft will not have its full force in gm'ng lthrough the window opening. j

When it is desired to adjust the window shades vertically with respect to the window constructiongthe guide arms are moved, in a manner herein set forth, from bearing relation within the intermeditate guide channels 15. Theshades are then lowered in unison and when in proper or' predetermined lowered position the guide arms 39 are permitted to move intok bearing relation w'ith respect to the intermediate channels 15. This disposes the retaining plates 45 against thebight portions of the channels and any '100 tendency of winding movement of the shades about the rollers 17 by action of the springs 22 will cause theretaining plates to wedge between within the bight portions ot the channels thus releasably latching the shades in a proper adjusted position.

By the novel connectionbetw'een the outer shades 24 and the sti'ening roller 34' it will be seen th'at the shades may be adjusted relative to each other whereby to dis- 11o the sleeve in desired adjusted position to re- 115 tain the shade in predetermined adjusted'position with respect to each other.

Attention is directed tothe fact that the channels 15 are adjustably connected together through the medium of a back plate 14. This connection is such that the channels may be adjusted relatively to each other whereby to dispose the shademembers toward or away from eachother as required.

From the above description it will be manifest that my improved window shade construction will permit proper ventilation of a room. The arrangement permits atmospheric air to come into the room whileat the same time the shade members aord the Cil necessary shade protection when the shade members are pulled down and also obstructing view to the inside of the room as Well as from the inside to the outside ofthe room. Ventilation of the room by use of `my improved shade member may take place without fear of getting the, full force'of the draft upon ones person. This is due to the fact that the holes formed in the shade members are staggered with respect to each otherand as the draft enters through the holes the force ofthe draft is broken. IVhile I have illustrated and described the preferred form of construction. for carrying, my mvention into effect, this is capable of' variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth but desire to avail myself of such variations and modifications as come within the scope of .the appended claims.
